The degradable insert member (14) is substantially planar in contour and includes a plurality of through openings (24). Soap material is molded around the degradable insert member (14) and within the through openings (24). The soap material molded within the through openings (24) secures the degradable insert member (14) to the surrounding soap material and provides a mechanism for securing the degradable insert member (14) to the soap bar (12) independent of wear orientation imposed on the soap bar (12) during use.
